Easy Access Patch Panel

ABSTRACT

Technology allowing for easy access to connectors in a patch panel. In one of the configurations a patch panel includes at least one patch panel subassembly, each patch panel subassembly including at least one mounting plate and a plurality of port assemblies, the at least one mounting plate being configured to accommodate the port assemblies so that each port assembly can individually translate along a direction parallel to a surface of the mounting plate and can rotate about an axis perpendicular to the surface of the mounting plate.

BACKGROUND OF THE INVENTION

Patch panels are widely used in network systems to monitor, interconnect and test circuits. A patch panel generally consists of a two-sided array of connection ports that are adapted to receive communication lines, such as optical fiber cables. The connection ports may themselves be two-sided, with the cable inserted on one side of a given connection port being communicatively coupled to the cable inserted on the other side of the same connection port.

Patch panels have shrunken in size over time in order to conserve space. However, as the patch panel shrinks in size, it also becomes increasingly difficult to maintain the patch panel and manage the cable connections. The cables are connected and disconnected by manual latching mechanisms, and a user must be able to access the latching mechanisms in order to latch or unlatch a cable with its corresponding connection port.

In order to make the cable connections more accessible, the patch panel may be designed with sliding trays. The connection ports are built into the sliding trays, so that when a tray is slid out, the connection ports slide out with the trays. The sliding trays make the connection ports much more accessible since a single row of ports can be slid out of the array at a time, so that the rows of connection ports immediately above and below no longer interfere with access to the row of connection ports on the slid-out tray.

One tradeoff of the sliding tray design is that the cables connected to the connection ports must be extra-long in order to move in and out with the sliding tray, such that undesired bending stresses on cables caused by pulling on cables with the movement of the trays may be avoided. This excess length in the cables can itself make accessing the connection ports more difficult, especially in a high density patch panel configuration where space for running the lengths of cables extending from the connection ports is limited. Additionally, longer length cables are more liable to become tangled with one another.

Ultimately, access to the cable connections to manually latch and unlatch cables is an important feature of a patch panel, and providing cables that are as short as possible and do not have slack is also an important feature of the patch panel. But there is a tradeoff between these features, since the cable slack is needed in order to pull a row of connection ports out to make them more accessible.

Therefore, an improved patch panel is desired that provides for ease of access to cable connections to connectors of the patch panel while minimizing lengths of cables extending from the connectors at the patch panel.

DETAILED DESCRIPTION

FIGS. 1, 2 and 3 illustrate a patch panel 100 from various angles. FIG. 1 is a perspective view of the patch panel. FIG. 2 is a top view of the patch panel. FIG. 3 is a front view of the patch panel. Each of FIGS. 1-3 is provided with a coordinate space key [x,y,z] to clarify the relationships between the relative views.

The patch panel 100 may include a frame 110 having a frame-depth in a direction of axis x, a frame-width in a direction of axis y, and a frame-height in a direction of axis z. The frame 110 may be made of a sturdy supporting material such as metal or a heavy-gauge plastic.

The patch panel 100 further may include a plurality of trays 120 supported by the frame 110 and stacked vertically in the frame-height direction. In the present example, the trays 120 do not rest directly on top of each other or otherwise directly touch one another, such that any one tray may be pulled out of the patch panel 110 array without moving or touching the other trays. In the present example, three trays are stacked one on top of another, although in other examples more or fewer trays may be stacked. Additionally, in the present example, the two stacks of trays are arranged adjacent to one another, although in other examples, there may be only one stack of trays, or there may be more than two adjacent stacks of trays.

Each of the trays 120 may be substantially the same as one another. For purposes of clarity, the description below explains the structure and function of a single tray 120 in the middle of a vertical stack of trays, but it should be understood that the same structure and function may apply to each of the trays in the vertical stack.

The tray 120 may be positioned inside the frame 110. The frame 110 is open on each of a first side 112 and an opposing second side 114 along the frame-depth direction, such that the tray may be accessed from either side of the frame 110.

A plurality of connection ports 130 may be connected to the tray 120. In the present example, the tray may include a row of twelve connection ports 130 aligned in the frame-width direction, although more or fewer connection ports may be included in other examples. The connection ports are two-sided and configured to receive cable connection terminals 140 from either side 112, 114 of the frame 110.

Each of the connection ports 130 and cable connection terminals 140 may be substantially the same as one another. For purposes of clarity, the description below explains the structure and function of a single connection port 130 and a single cable connection terminal 140, but it should be understood that the same structure and function may apply to each of the connection ports and connection terminals included in the tray.

The cable connection terminal 140 may include a rigid housing 142 configured to attach to and partially house a cable 150. The rigid housing 142 may be adapted to fit into an opening in the connection port 130. In the present example, fitting cable connection terminals into opposite sides of a connection port 130 causes the cables housed by the respective cable connection terminals to be communicatively coupled to one another.

The cable connection terminal 140 may also include a dis-latching mechanism 144 or more generally a latch. The dis-latching mechanism 144 may be provided on an outer surface of the rigid housing 142. The dis-latching mechanism 144 may be a depressible finger adapted to engage a recessed edge of an inner surface of the connection port 130. When the dis-latching mechanism 144 is engaged, it may prevent the cable connection terminal 140 from disconnecting from the connection port 130. The dis-latching mechanism 144 may be disengaged manually, such as by a user pressing, pulling, or twisting the dis-latching mechanism 144. Screws, bolts, springs, or other well-known cable locking devices and mechanisms may be used to achieve similar results. Further, in other examples, the latch may be provided on the connection port 130 itself, such that disengaging the latch on the connection port may cause a cable connection terminal inserted in the connection port to become disconnected.

The cable connection terminal 140 may further include a flexible boot 146 positioned between the rigid housing 142 and an exposed, non-housed portion of the cable 150. The boot may be flexible in order to improve durability of the cable connection terminal 140 and ensure that the cable 150 does not become disconnected from the patch panel 100. The boot provides strain relief, preventing the cable 150 from being bent sharply as such sharp bending could cause the inner fiber to be broken and result in transmission loss.

When inserted into the connection port 130, the cable connection terminals 140 on either side of the connection port 130 may extend away from the connection port 130 along a first axis. In the example of FIGS. 1-3, the first axis may be the same as the frame-depth direction x. However, in other examples, the first axis may be angularly offset from the frame-depth direction, such that the cable connection terminals enter the connection ports at an angle relative to the frame depth direction.

Returning to the tray 120, the tray may be supported by guides 116 on one or both sides of the frame 110. The guides 116 may extend along a second axis angularly offset from the first axis. In FIG. 2, a second axis x′ is shown, and is angularly offset from the frame-depth direction x. However, in those examples where the first axis is itself angularly offset from the frame-depth direction x, the second axis may be the same direction as the frame-depth direction.

The tray 120 may be adapted to slide along the guides 116, such that the tray moves in either direction in the direction of axis x′. This is noticeable from the top view illustration of FIG. 2, in which the tray 120 is parallelogram-shaped such that the side edges of the tray extend in the x′ axis direction and may slide in the direction x′ offset from the frame-depth direction x. It can be further seen from FIG. 2 that the side edges of the frame 110 (and impliedly the guides 116 of the frame) may extend in the same direction as the side edges of the tray 120, as opposed to the direction in which the cable connection terminals 140 extend. As explained in greater detail below, the angling of the frame 110, guides 116 and tray 120 are important for making the dis-latching mechanism 144 on the cable connection terminal 140 accessible without having to pull the tray from an interior of the patch panel frame to a position where the cable connection terminal 140 is completely out of the patch panel 100.

The cable connection terminals 140 in the present illustrated example are multi-fiber push-on (MPO) cable terminals (also referred to as MTP cables), and the cables 150 connected to the terminals are multi-fiber cables. In the example of MPO cable terminals, the connection port may include a hook affixed to an inner surface of the port, and the cable connection terminal may include a corresponding latch configured to be secured by the hook. Securing the latch to the hook may result in the cable connection terminal being operatively connected to the patch panel connection port. The connection port may further be configured to release the latch when the latch is slid out of the hook. In other examples, other types of cables and terminals may be used. For instance, any known fiber cable (e.g., single core fiber cable) and any known connector having a latch or other mechanism for connecting and disconnecting the cable from a port (e.g., an SC connector) may be compatible with a patch panel designed according to the present disclosure.

FIG. 4 is a perspective view of an example tray 120 and shows the structure of the tray in greater detail. The tray 120 includes a surface 410 defining a surface plane. The surface plane may be a plane in the frame-width and frame-depth directions. A vertical member 420 may extend vertically from the surface in the frame-height direction, separating the first side 112 from the second side 114 of the tray 120. The vertical member 420 may span the entire or close to the entire width of the surface 410, and may include apertures 430 aligned in a single row across the width of the surface 410. Each aperture 430 may be occupied by a respective two-sided connection port 130, such that a first side of the connection port 130 is positioned on the first side 112 of the tray 120, and a second side of the connection port 130 is positioned on the second side of the tray 120. In the example of FIG. 4, the vertical member 420 extends upward and the connection ports 130 are positioned above the surface 410, although in other examples the vertical member may extend downward with the connection ports positioned below the surface.

In each of FIGS. 1-3, all of the trays 120 of the patch panel 100 are in a tray-in position. Each of the rows of cable connection terminals 140 are aligned vertically in the frame-height direction with one another. The tray-in position is generally suitable for storage of the trays, with each of the cable connection terminals 140 being made inaccessible such that the terminals are not readily disconnectable from the patch panel 100 in such position.

FIGS. 5, 6 and 7 show the patch panel 100 having a tray 120 in a tray-out position from various angles. FIG. 5 is a perspective view of the patch panel. FIG. 6 is a top view of the patch panel. FIG. 7 is a front view of the patch panel. Each of FIGS. 5-7 is provided with a coordinate space key [x,y,z] to clarify the relationships between the relative views.

As described below, the tray-out position is a position of the tray that is generally suitable for accessing the cable connection terminals 140 of the slid-out tray, provided that the trays immediately above and below the slid-out tray 120 are still in the tray-in position or otherwise not aligned vertically with the slid-out tray. Sliding out the tray 120 may involve pulling or pushing the tray 120 from the first side 112, or pulling or pushing the tray 120 from the second side 114. The tray 120 may be adapted to glide or roll or otherwise slide on the guides 116 to move between the tray-in and tray-out positions.

The tray 120 slides from the tray-in position to the tray-out position along an axis that is parallel with the second axis (e.g., x′ in FIG. 6) along which the opposing side edges of the tray 120 extend and parallel with the surface of the tray 120, where the second axis is angularly offset from the first axis (e.g., x in FIG. 6). This results in the cable connection terminals of the slid-out tray being laterally displaced relative to their position in the tray-in position. Stated another way, any given cable connection terminal may be thought of as extending co-extensively with a first line in the direction of the first axis when in the tray-in position, and as extending co-extensively with a parallel but offset second line in the direction of the first axis when in the tray-out position. When the tray is in the tray-out position, the distance between the first line and the second line may be d/2, which is half the distance d between adjacent cable connection terminals.

In particular, in the example of FIGS. 5-7, the tray 120 is adapted to slide at an angle relative to the frame-depth direction. This results in the cable connection terminals becoming displaced in each of the frame-width direction and the frame-depth direction when the tray moves from the tray-in position to the tray-out position. Additionally, when the tray reaches the tray-out position, the cable connection terminals 140 of the slid-out tray 120 may become laterally offset in the frame-width direction relative to the cable connection terminals of the trays immediately above and below the slid-out tray 120. To obtain the tray at the tray-out position from the tray-in position, the tray is slid a minimum distance that the tray needs to be slid from the tray-in position in a direction along an axis parallel to the second axis, to provide that the tray is positioned to permit access to its cable connection terminals. Thus, at the tray-out position, the cable connection terminals of the tray may be accessed, such that there is no need to slide the tray a further distance along the guides out of the patch panel to provide for access to the cable connection terminals. At the tray-out position, the lateral offset may be half (d/2) the lateral distance between adjacent cable connection terminals (d).

Thus, as shown in each of FIGS. 6 and 7, when the tray 120 reaches the tray-out position, the cable connection terminals 140 of the slid-out tray 120 are laterally positioned above and beneath the gaps between cable connection terminals of the trays immediately above and below. This makes accessing the cable connection terminals 140 of the slid-out tray 120 possible.

Since the cable connection terminals 140 of the slid-out tray 120 at the tray-out position can be accessed through gaps immediately above and below, it is not necessary for the tray 120 to slide out very far. In particular, the displacement of the tray between the tray-in and tray-out positions may be less than the length of the cable connection terminals in the direction of the first axis. For example, if each cable connection terminal is 100 millimeters long, the displacement between the tray-in and tray-out positions may be less than 100 millimeters long, and in some examples, 50 millimeters or less.

In one example, the frame 110 shown in the example of FIGS. 1-7 may be between about 400 millimeters to about 500 millimeters wide, and each tray 120 may be about 200 to 250 millimeters wide. The twelve cable connection terminals 140 may be spaced apart by about 15 to about 25 millimeters (including the width of the cable connection terminals themselves). The spacing may be the same or similar for trays having a different number of cable connection terminals. The height of the frame may be between about 40 millimeters and about 45 millimeters, meaning that each tray is separated by a gap of less than 15 millimeters. This makes it difficult for a user to access the latches on the cable connection terminals 140 without moving the tray 120 to a tray-out position.

Generally, the tray 120 may have two tray-out positions, a first tray-out position in which the cable connection terminals on the first side 112 of the tray 120 are made accessible, and a second tray-out position in which the cable connection terminals on the second side 114 of the tray 120 are accessible. The tray may slide from the tray-in position to either one of the tray-out positions depending on the direction (e.g., forward vs. back) that the tray is slid. In either case, the position of the tray may be moved in a direction of the second axis angularly offset from the first axis (e.g., in the case of FIGS. 5-7, moved in both the frame-depth direction and the frame-width direction) in order to make the cable connection terminals at respective sides of the tray more accessible.

The patch panel may include additional features to improve its function and operation, as well as the accessibility of the cable connection terminals. FIG. 8 is a perspective view of an underside 810 of the tray 120 from FIG. 4. As can be seen from FIG. 8, the surface 410 of the tray 120 may include a pair of slot-shaped openings 812 and 814 extending in the frame-width direction. A first opening 812 may be positioned directly underneath the rigid housing of the cable connection terminal on the first side 112 of the tray 120. A second opening 814 may be positioned directly underneath the rigid housing of the cable connection terminal on the second side 114 of the tray 120.

In the example of FIG. 8, the second opening 814 is made large enough for the vertical member 420 to be vertically aligned in the frame height direction with an inside edge 824 of the second opening 814. However, in other examples, the second opening may be made smaller, so long as the opening remains large enough to permit access to the latch or other connection/disconnection mechanism on the rigid housing of the cable connection terminal.

Additionally, in the example of FIG. 8, the openings 812, 814 are positioned underneath the rigid housings of the cable connection terminals. However, in those examples where the connection/disconnection mechanisms are positioned elsewhere, such as on the connection port, the openings in the tray surface may be positioned differently in order to be properly aligned with the respective connection/disconnection mechanisms. In the example of FIG. 8, the opening 812 is purposely aligned with dis-latching mechanism 144 to allow for easy dis-latching of the cable connection terminal 140 from the connection port 130.

FIGS. 1, 3, 5 and 7 also show a mechanical stopper 160 configured to prevent the trays from accidentally sliding out of the frame. A close-up of the mechanical stopper is shown in each of FIGS. 9A and 9B.

The mechanical stopper 160 may be mounted to an outer surface of the frame 110 and extending from the frame in a frame-depth direction. The mechanical stopper 160 may include one or more notches 920 notched into the body of the stopper in the frame-width direction such that the width of the mechanical stopper 160 in the frame-width direction is shorter at the location of the notches 920 than at portions of the stopper 160 above and below the notches. In this regard, the mechanical stopper 160 may have an overall width that overlaps in the frame-width direction with at least a portion of the trays 120, but the width of the mechanical stopper 160 at the location of the notches does not overlap in the frame-width direction with the trays 120.

In FIG. 9A, the mechanical stopper 160 is in a locked position. The notches 920 are vertically out of alignment with the guides 116 of the frame 110, thus preventing each of the trays 120 from sliding between the tray-in position and a tray-out position. In FIG. 9B, the mechanical stopper 160 is in an unlocked position. The notches are vertically aligned in the frame-height direction with the guides 116 of the frame 110, leaving each of the trays 120 free to slide between the tray-in position and a tray-out position.

In the examples of FIGS. 9A and 9B, moving the mechanical stopper 160 between the locked and unlocked positioned may involve displacing the mechanical stopper 160 vertically in a frame-height direction. The mechanical stopper 160 may be biased to the locked position by a biasing element, such as a bias spring 930. The bias spring 930 may exert a force on the mechanical stopper 160 in the vertical frame-height direction. The bias spring 930 may be configured to be depressible, such that an opposing force (in the example of FIG. 9, an upward force) compresses the bias spring 930 and displaces the mechanical stopper 160 along the axis of the bias spring force until the notches 920 become aligned with one or more trays 120 in the frame 110.

Additionally, the trays 120 may be configured to overlap with the mechanical stopper 160 in the frame-height direction when slid to a tray-out position, but not in the tray-in position. Because of the overlap, a tray 120 in a tray-out position may block the mechanical stopper 160 from returning to its biased locking position. The mechanical stopper 160 would then return to the locking position only after the tray 120 has been returned to its tray-in position and no longer overlaps with the mechanical stopper in the frame-depth direction, leaving the bias spring 930 free to bias the mechanical stopper 160 into the locking position.

FIGS. 4 and 8 also show an anchor member configured to anchor the tray to the frame. A close-up of the anchor member is shown in FIG. 10. The anchor 1010 may be appended to an edge of the tray surface 410 extending from the tray surface 410 in a frame-width direction. The anchor 1010 may have a height in the frame-height direction that is greater than a thickness of the tray surface 410. Additionally, the guides 116 in the frame 110 may be slots, whereby each slot has a width equal or greater than the thickness of the tray surface 410 but less than the height of the anchor 1010. In this regard, the tray 120 may slide forward and back along the x′ axis along the slot 116, but the anchor prevents from the tray 120 from rotating or otherwise sliding side-to-side in the frame-width direction out of the frame 110.

In the instance of a patch panel with two-sided connection ports and trays that may slide out both forward and back, the mechanical stoppers and anchors may be provided on both sides of the patch panel. For instance, a first mechanical stopper on a first side of the frame may prevent the trays from sliding out in the direction of the first side, and a second mechanical stopper on a first side of the frame may prevent the trays from sliding out in the direction of the second side. Likewise, each tray surface may be equipped with two anchors, one anchor on the first side to prevent side-to-side sliding when one side of the tray is pulled out, and the other anchor on the other side of the tray for when the other side of the tray is pulled out.

FIG. 11 shows an alternative embodiment of a patch panel 1100 according to the present disclosure. Like the prior embodiment, the patch panel 1100 of FIG. 11 includes a frame, trays, connection ports (72 ports in the example of FIG. 11, just like the prior illustrated examples), and cable connection terminals for connecting cables to the connection ports. The patch panel 1100 in FIG. 11 differs in that each of the trays is configured to both rotate and slide out.

The frame 1110 may include a post 1118 extending vertically in the frame-height direction. In some instances, the post 1118 may be in proximity to a sidewall of the frame 1110. Each of the trays 1120 may also include an elongated slot 1122 etched into the surface of the tray 1120. The elongated slot 1122 may be adapted for the post 1118 to be inserted into the slot 1122, such that the tray 1120 may rotate about a pivot point in the slot 1122 (e.g., the post 1118) and may slide in the direction of the elongation of the slot. In this regard, the width of the slot 1122 may be about or only slightly wider than the width of the post 1118, in order that the tray 1120 neatly fits on and slides relative to the post 1118. In some instances, the slot 1122 may be L-shaped.

The post 1118 may further include a supporting feature such as a platform or spacer on which the weight of the tray may be supported and to provide that the trays 1120 received by the frame 1110 may be spaced apart vertically to avoid interference between adjacent ones of the trays.

The frame 1110 may further include a shaft (not shown) or other cable routing location in proximity to the post 1118. One or more cables 1119 from the patch panel 1100 may be routed through the shaft. In this manner, for a given cable 1119, the distance from the cable connection terminal to the shaft does not significantly change as the tray 1120 rotates about the post 1118. Additionally, since the tray 1120 slides in and out only a short distance (e.g., fewer than 100 millimeters, about 50 millimeters), the positional translation of the tray 1120 also does not significantly affect the distance from the cable connection terminal to the shaft.

In operation, moving a tray in the frame 1110 of FIG. 11 from the tray-in position to the tray-out position may involve both rotating the tray around the post 1118 and translating the tray in the direction of the slot 1122 elongation along a plane defined by the tray surface. The purpose of rotating the tray is to move the cable connection terminals of the rotated tray out of vertical alignment with the cable connection terminals of the trays immediately above and below. The purpose of translating the tray is to create additional clearance and accessibility for the cable connection terminals closest to the post 1118 (since rotating those terminals repositions them less than rotating the terminals farther from the post 1118).

The rotatable trays may be configured to rotate in opposing directions so that the cable connection terminals on either side of the corresponding connection ports may be made accessible. Each of the stacked trays may be configured to rotate about a pivot point (e.g., the post) and translate along an axis of a length of the elongated slot. For instance, as shown in FIG. 11, a first tray 1141 is shown rotated in one direction, and a second tray 1142 is shown rotated in an opposite second direction. It may also be noted that the first tray 1141 is also translated along the elongated slot, whereas the second tray 1142 has not been translated.

As can be seen from FIG. 11, the elongated slot 1120 in the tray 1120 may be formed in an extension of the tray surface that protrudes beyond the width of the frame 1110. This may allow for the post 1118 to be formed close to an edge of the frame 1110 in the frame-width direction, while maintaining only a small portion of the tray surface on an opposite side of the post 1118 in the frame-width direction, while also providing for the tray 1120 to be able to rotate about the post 1118.

Referring now to FIG. 12, there is shown a perspective view of a patch panel tray 1200 according to an embodiment. The patch panel tray 1200 is similar to each of the trays 120, with the exception that tray 1200 includes one or more handles 1205. In the figure, two handles 1205 are depicted, one on the first side 112 of the tray and one on the second side 114 of the tray. However, it should be noted that the tray 1200 may be configured to have a single handle on, for example, the first side 112 of the tray, or may be configured to have more than two handles. In any event, the handles facilitate positioning the tray 1200 in the tray-in and tray-out positions by providing a place for a user to grab the tray 1200. A multiple of trays each configured like tray 1200 may be substituted for each of the multiple of trays 120 in the embodiments of FIGS. 1-10, for example, to realize alternative embodiments. As in trays 120, in tray 1200 a vertical member 420 of may extend vertically from the surface in the frame-height direction, separating the first side 112 from the second side 114 of the tray 1200. The vertical member 420 may span the entire or close to the entire width of a surface 410, and may include apertures 430 aligned in a single row across the width of the surface 410. Each aperture 430 may be occupied by a respective two-sided connection port 130, such that a first side of the connection port 130 is positioned on the first side 112 of the tray 120, and a second side of the connection port 130 is positioned on the second side of the tray 120. In one configuration, the vertical member 420 extends upward and the connection ports 130 are positioned above the surface 410, although in other examples the vertical member may extend downward with the connection ports positioned below the surface.

Turning to FIG. 13, there is shown a perspective view of a patch panel configuration according to an embodiment having trays 1305 a, 1305 b, 1310 a, 1310 b, 1315 a, and 1315 b arranged in pairs. For example, trays 1305 a and 1305 b make up a pair. Each pair of trays has an associated multiple of intermediate cables, or “jumper” cables, although for clarity of presentation FIG. 13 shows only intermediate cables 1320, which are associated with tray pair 1305 a, 1305 b. Further, each two trays that make up a pair may be coplanar, or substantially coplanar, and the cables connecting such trays may be maintained in the plane, or substantially in the plane, of the trays by a support. For example, trays 1305 a and 1305 b may be coplanar in a plane parallel to the XY plane, and the cables 130 may be maintained in the plane of trays 1305 a and 1305 b by a support 1330. The support 1330 may be mounted, for instance, on an enclosure that encloses the trays 1305 a, 1305 b, and cables 1320.

Each of the trays 1305 a-1315 b includes a respective multiple of ports. For example, tray 1305 a includes ports 1340 a, and tray 1305 b includes ports 1340 b. Each of the ports 1340 a and 1340 b may accept one or more connection terminals for coupling to respective external cables 1320. Moreover, cables 1320 may themselves be coupled to the ports by respective connection terminals. Thus, in one embodiment, each of cables 1320 has a connection terminal at a first end 1320 a of the cable, e.g., cable 1322, and a connection terminal at a second end 1320 b of the cable, e.g., cable 1322, and the connection terminal at first end 1320 a is coupled to one of ports 1340 a and the connection terminal at second end 1320 b is coupled to a corresponding one of ports 1340 b. Pairs of external cables, e.g., cables 1350 and 1355, may then be coupled to each other through a respective one of cables 1320, e.g. through the one of ports 1340 a and the corresponding one of ports 1340 b.

In the arrangement of FIG. 13, the connection terminal attached to cable 1350 may be easily accessed by moving tray 1305 a along the Y direction to a tray-out position, without disturbing cable 1355. That is, the intermediate cables 1320 are provided in sufficient length to accommodate movement of tray 1305 a without exposing cable 1355 or tray 1305 b to any significant force resulting from such movement. Similarly, the connection terminal attached to cable 1355 may be easily accessed by moving tray 1305 b along a direction opposite the Y direction to a tray-out position, without disturbing cable 1350 or tray 1305 a.

FIG. 14 is a perspective view of the patch panel configuration of FIG. 13 as arranged in an enclosure 1400. The enclosure may enclose all of trays 1305 a-1315 b and may include one or more guides, e.g., guides 1405 a, 1405 b, 1410 a, and 1410 b, for guiding the trays during movement between a tray-in position and a tray-out position. For example, tray 1305 a may be guided between a tray-in position and a tray-out position by guides 1405 a and 1410 a. In addition, the guides may be associated with respective stops, e.g., stops 1420 a, 1420 b, 1425 a, and 1425 b. The stops are provided for limiting movement of the trays past a designated tray-in position. For example, stops 1420 a and 1425 a prevent tray 1305 a from moving past a designated tray-in position.

FIGS. 15A and 15B show two paired tray patch panel arrangements 1500A and 1500B in a side by side configuration, with paired tray patch panel arrangement 1500A having both trays 1505 a and 1505 b in a tray-in position and paired tray patch panel arrangement 1500B having a tray 1510 a in a tray-in position and a tray 1510 b in a tray-out position. The two paired tray patch panel arrangements 1500A and 1500B may be included in a frame (not shown), which may be integral with a panel enclosure (not shown), attached to the panel enclosure, or separate from the panel enclosure. Each of arrangements 1500A and 1500B may be supported by the frame and stacked in a first direction, e.g., the Z direction, with other paired tray arrangements. Further, each of arrangements 1500A and 1500B are configured to receive respective pairs of cable connection terminals so that, for each pair of cable connection terminals received by the arrangement, one of the cable connection terminals is received by a first tray of the pair of trays, a second of the cable connection terminals is received by a second tray of the pair of trays, and the first cable connection terminal and the second cable connection terminal are configured to be communicatively coupled to each other by an intermediate cable such that the cable connection terminals extend outward from each other in a direction of a first axis. For example, arrangement 1500A is configured to receive a first cable connection terminal 1512 a at a port of tray 1505 a and receive a second cable connection terminal 1512 b at a port of tray 1505 b, and cable connection terminal 1512 a and cable connection terminal 1512 b are communicatively coupled to each other by an intermediate cable 1520 such that the cable connection terminals 1510 a and 1510 b extend outward from each other along the Y axis.

In the FIG. 15A, 15B embodiment, first cable connection terminals, e.g., first cable connection terminal 1512 a, are coupled to respective ports of tray 1505 a, e.g., port 1525 a, and second cable connection terminals, e.g., second cable connection terminal 1512 b, are coupled to respective ports of tray 1505 b, e.g., port 1525 b. Also, a first end of each intermediate cable, e.g., end 1520 a of cable 1520, is coupled to a first intermediate cable connection terminal, e.g., first intermediate cable connection terminal 1530 a, which is in turn coupled to a respective port of tray 1505 a, e.g., port 1525 a; and a second end of each intermediate cable, e.g., end 1520 b of cable 1520, is coupled to a second intermediate cable connection terminal, e.g., first intermediate cable connection terminal 1530 b, which is in turn coupled to a respective port of tray 1505 b, e.g., port 1525 b. In this manner a cable connected to one of the first cable connection terminals may be coupled to a cable connected to one of the second cable connection terminals by way of an intermediate cable. For example a cable coupled to first cable connection terminal 1510 a may be coupled to a cable connected second cable connection terminals 1510 b by first cable connection terminal 1510 a, port 1525 a, first intermediate cable connection terminal 1530 a, intermediate cable 1520, second intermediate cable connection terminal 1530 b, port 1525 b, and second cable connection terminal 1510 b.

Portions of the intermediate cables 1520 of the FIG. 15A, 15B embodiment are positioned within a cable jacket 1540. The jacket 1540 facilitates coordinated positioning of the intermediate cables 1520 in a space between trays 1505 a and 1505 b. Further, the jacket is held by a support 1550, which restrains the jacket and, in turn, the intermediate cables in at least one direction.

Referring now to FIG. 15B, paired tray patch panel arrangement 1500B is shown with tray 1510 a in a tray-in position and tray 1510 b in a tray-out position. Arrangement 1500B is the same as arrangement 1500A, except with respect to the X axis. Along the X axis, arrangement 1500B mirrors arrangement 1500A. As can be seen from FIG. 15B, movement of tray 1510 b to the tray out position does not cause any significant force to be exerted on tray 1510 a due to the slack in intermediate cables 1560. That is, as tray 1510 b is moved in the Y direction, intermediate cables 1560 and associated jacket 1565 accommodate such movement. Moreover, a support 1570 support cables 1560 and jacket 1565 along the Z direction. The support 1570 holds the cables 1560 and jacket 1565 and is free to move in an XY plane but not along the Z axis such that cables 1560 and jacket 1565 are free to move in an XY plane but restrained from movement along the Z axis.

Arrangement 1500B may be stacked in a first direction, e.g., the Z direction, with other paired tray arrangements. In such configuration, tray 1510 b may be adapted to slide between a first tray-in position and at least one first tray-out position by sliding parallel to, or substantially parallel, to trays in the other paired tray arrangements while the tray 1510 a does not move.

Referring now to FIGS. 16A-16F are perspective views of a paired tray patch panel 1600 according to an embodiment. FIG. 16A shows an enclosure 1605 of the patch panel 1600. The enclosure includes a top 1610, cable hangers 1615, and doors 1620. The cable hangers 1615 are provided for securing cables running to and from the patch panel. The doors 1620 are provided to secure slidable trays within the enclosure 1605, and may be opened to allow the trays to slide outward from the enclosure 1605.

FIG. 16B shows the patch panel of FIG. 16A with portions, including top 1610, removed. The patch panel includes a first paired tray patch panel arrangement 1625A and a second paired tray patch panel arrangement 1625B. In one possible embodiment the arrangements 1625A and 1625B may respectively take the form of arrangements 1500A and 1500B (as shown in FIGS. 15A and 15B). In any event, arrangement 1625A includes a first tray 1630 a, a second tray 1630 b and intermediate cables (not shown) which run through a cable jacket 1635. Similarly, arrangement 1625B includes a first tray 1640 a, a second tray 1640 b and intermediate cables (not shown) which run through a cable jacket 1645. In addition, each of trays 1630 a, 1630 b, 1640 a, and 1640 b includes a handle, e.g., handle 1650, for easy manipulation of the tray. As can be seen in FIG. 16B, the patch panel includes sidewalls 1660 and 1665, and a middle wall 1670. The walls 1660, 1665, and 1670 have corresponding guides, e.g., multiple guides 1675 on sidewall 1660, which guide movement of the trays of the patch panel, e.g., trays 1630 a and 1630 b, between tray-in positions and tray-out positions. In FIG. 16B only two paired tray patch panel arrangements are shown, however the patch panel of the figure is configured to include six paired tray patch panel arrangements, stacked in three layers with two paired tray arrangements configured side by side in each layer. The layers proceed upwards from arrangements 1625A and 1625B toward the top of the enclosure such that each layer corresponds to one of guides 1675.

FIG. 16C shows an alternate view of the layout of FIG. 16B. As can be seen from FIG. 16C, middle wall 1670 includes guides 1680 a, 1680 b, and 1680 c. Each of guides 1680 a, 1680 b, and 1680 c each correspond to a layer of two paired tray arrangements. Thus, for example, guide 1680 a corresponds provides guidance for trays 1630 a and 1630 b of arrangement 1625A. As can be further seen from FIG. 16C, each of the cable jackets, e.g., cable jacket 1635, are supported by respective pairs of supports, e.g., supports 1685 a and 1685 b, which restrain the cable jacket, and intermediate cables inside the jacket, from moving in a direction along the top to bottom direction of the enclosure 1605 while allowing the jacket and cables to move in a direction perpendicular to the top to bottom direction of the enclosure 1605. FIG. 16C also shows a center stopper 1690 on sidewall 1665. The center stopper 1690 is provided to limit movement of trays guided by guides 1677, e.g., tray 1640 a, when the trays are moved toward the enclosure 1605. FIG. 16D provides a detail view of a center stopper 1695 on sidewall 1660.

FIG. 16E shows an alternate view of the layout of FIGS. 16B and 16C. In FIG. 16E tray 1640 b appears at the lower left portion of the figure. Tray 1640 b is shown in isolation in FIG. 16F. As can be seen from FIG. 16F, tray 1640 b includes a lid 1640 b′ which may be opened to expose a multiple of ports 1640 b″. In one embodiment, each of the ports 1640 b″ may be the same as port 1525 a (shown in FIG. 15A).

FIG. 17 is a top view of a paired tray patch panel configuration 1700 according another embodiment. The FIG. 17 configuration is similar to the embodiment discussed in connection with FIGS. 16A-16F, except with regard to intermediate cable management. The embodiment of FIG. 17 further reduces the risk that movement of one tray in a pair will interfere with cable connections on the other tray in the pair. For example, the embodiment features cable management that further reduces the risk that movement of tray 1640 b from its tray-in position (shown) to its tray-out position (not shown) will interfere with cable connections on tray 1640 a. More specifically, intermediate cables that couple connection terminals on tray 1640 b to connection terminals on 1640 a are routed through a cable jacket 1705 which is secured to a wall 1710 of the patch panel configuration by a sleeves 1715 a and 1715 b. Thus, when either, or both, of trays 1640 a and 1640 b move the jacket and cable portions farthest from the trays 1640 a and 1640 b do not move, thereby insulating movement of the trays 1640 a and 1640 b from each other. In addition, the FIG. 17 embodiment includes pivoting supports 1720 a and 1720 b to support the cable jacket 1705 such that the jacket can move in a direction parallel, or substantially parallel, to a floor 1735 of the patch panel configuration 1700 but not in a direction perpendicular, or substantially perpendicular to the floor 1735.

FIG. 18. is a top view of a paired tray patch panel configuration 1800 according to an embodiment in which all cable access is from the front of the patch panel. The FIG. 18 configuration includes first tray 1805 a having cable connection terminals 1810 a and a second tray 1805 b having cable connection terminals 1810 b. The trays 1805 a and 1805 b are positioned such that both terminals 1810 a and 1810 b face a same side of the configuration 1800, e.g., a front side 1820 of the configuration 1800. Cables connected to respective ones of terminals 1810 a are communicatively coupled to cables connected to respective ones of terminals 1810 b via ports 1825 a of tray 1805 a, intermediate cable connection terminals 1830 a, intermediate cables 1835, intermediate cable connection terminals 1830 b, and ports 1825 b of tray 1805 b. The embodiment of FIG. 18 allows each of tray 1805 a and 1805 b to be moved from their tray-in position (shown) to a tray-out position without disturbing the other tray. In the embodiment as depicted, moving either of tray 1805 a or 1805 b to a tray-out position involves moving tray 1805 a or 1805 b along the Y direction.

To reduce risk that movement of tray 1805 a or 1805 b will interfere with cable connections on the other tray, the intermediate cables 1835 are routed through cable jackets 1840 a and 1840 b which are secured to a wall 1845 of the patch panel configuration 1800 by respective sleeves 1850 a and 1850 b. Thus, when either, or both, of trays 1805 a and 1805 b move the jackets 1840 a and 1840 b and cable portions farthest from the trays do not move, thereby insulating movement of the trays 1805 a and 1805 b from each other. In addition, the FIG. 18 embodiment includes pivoting supports 1855 a and 1855 b to respectively support the cable jackets 1840 a and 1840 b such that the jackets can move in a direction parallel, or substantially parallel, to a floor 1860 of the patch panel configuration 1800 but not in a direction perpendicular, or substantially perpendicular to the floor 1860.

FIG. 19A is a top view of the paired tray patch panel of FIG. 18 with tray 1805 b in a tray-out position. As can be seen by from the figure, pivoting support 1855 b has pivoted to accommodate the tray-out position of tray 1805 b and attendant position of cable jacket 1840 b while supporting the cable jacket 1840 b in a direction parallel, or substantially parallel, to floor 1860. As can be further seen from the figure, when tray 1805 b is in the tray-out position the cable jacket 1840 b remains secured to the wall 1845 by sleeve 1850 b.

FIG. 19B is a top view of the paired tray patch panel of FIG. 17 with a tray 1640 c in a tray-out position. As can be seen by from the figure, a pivoting support 1720 c has pivoted to accommodate the tray-out position of tray 1640 c and attendant position of cable jacket 1707 while supporting the cable jacket 1707 in a direction parallel, or substantially parallel, to a floor 1735 of the patch panel configuration 1700. As can be further seen from the figure, when tray 1640 c is in the tray-out position the cable jacket 1707 remains secured to the wall 1710 by sleeve 1715 c.

FIG. 20A is a top view of the paired tray patch panel of FIG. 18 with both tray 1805 a and tray 1805 b in tray-out positions. As can be seen, pivoting supports 1855 a an 1855 b have pivoted to respectively accommodate the tray-out positions of trays 1805 a and 1805 b while respectively supporting the cable jackets 1840 a and 1840 b in a direction parallel, or substantially parallel, to floor 1860.

FIG. 20B is a top view of the paired tray patch panel of FIG. 17 with both tray 1640 c and a tray 1640 d tray-out positions. As can be seen, pivoting supports 1720 c and 1720 d have pivoted to respectively accommodate the tray-out positions of trays 1640 c and 1640 d while respectively supporting cable jackets 1707 and 1708 in a direction parallel, or substantially parallel, to floor 1735.

FIG. 21 is a perspective view of a rack mount patch panel unit 2100 according to an embodiment. The unit 2100 includes three patch panel subassemblies 2105 a, 2105 b, and 2105 c, stacked in a first direction, the Z direction in the figure. Each patch panel subassembly includes at least one mounting plate, which is a type of mounting means of this disclosure, and a plurality of port assemblies. For example, subassembly 2105 a includes a plurality of port assemblies 2110 a, 2110 b . . . 2110 n, and mounting plate 2115 a. The mounting plate 2115 a is configured to accommodate the port assemblies 2110 a-2110 n so that each port assembly can individually translate along a direction parallel to a surface of the mounting plate, parallel to the direction X in the figure, and can rotate about an axis perpendicular to the surface of the mounting plate, about an axis in the direction Z in the figure. The port assemblies, e.g., port assemblies 2110 a-2110 n, are translatable and rotatable while keeping in contact with the mounting plates, e.g., mounting plate 2115 a.

The rack mount patch panel unit 2100 also includes a frame 2120 and a cable support 2125. The frame 2120 may be used to secure the mounting plates, e.g., mounting plate 2115 a, within the unit 2100, and to secure the unit 2100 to a rack (not shown) via mounts 2130 a and 2130 b. The cable support 2125 may be used to provide support in the Z direction for cables connected to the port assemblies, e.g. port assemblies 2110 a to 2110 n.

In the FIG. 21 configuration the port assembles, e.g. port assemblies 2110 a to 2110 n, have a common depth dimension 2132, shown by way of example in the figure. The depth dimension 2132 defines one dimension of space 2101 in which the port assemblies are arranged, The Y dimension of the space with reference to the figure. Accordingly, the Y dimension of the space is equal to depth dimension 2132 when all the port assemblies are aligned with their depths extending in the Y direction. Nevertheless, regardless of the port assemblies' orientations, the depth of the space 2101 (the Y extent of the space) is less than two times the depth dimension 2132 of the port assemblies.

The elements of the rack unit 2100 will be described in more detail below. In any event, it should be noted that the unit 2100 is not limited to three subassemblies, and that the unit 2100 may employee one subassembly, two subassemblies, or more than three subassemblies. Moreover, the unit 2100 may not include cable support 2125 or may include a cable support of a different configuration. Further, the unit 2100 may include a frame having a configuration different from frame 2120.

It should be further noted that for clarity of presentation the port assemblies, e.g., port assembly 2130 a, are depicted with cable connection terminals, e.g., cable connection terminals 2135 a, 2140 a, 2145 a, and 2150 a, inserted in the assemblies. The cable connection terminals are associated with respective cables (not shown) and each port assembly communicatively couples a cable connection terminal on one side of the assembly with a cable connection terminal on the other side of the assembly such that the cables corresponding to the two cable connection terminals are communicatively coupled. For example, port assembly 2130 a communicatively couples cable connection terminal 2135 a to cable connection terminal 2145 a. Moreover, it is noted that while the port assemblies are depicted as accommodating two cable connection terminals on each side, the embodiments are not limited to such assemblies. For instance, the port assemblies may accommodate one cable connection terminal on each side, or more than two cable connection terminals on each side.

The port assemblies may be secured in an elongated space. For example, the port assemblies in FIG. 21 are secured in space 2101, which is elongated in the X direction (the longitudinal direction). The longitudinal direction may be referred to as a first direction. Each port assembly at least one pair of front and rear ports, or interfaces, for accepting cable termination assemblies. For example, port assembly 2130 a includes front ports 2137 and 2139 for accepting cable connection terminals 2135 a and 2140 a, respectively, and includes rear ports 2142 and 2144 for accepting cable connection terminals 2145 a and 2150 a, respectively. The ports 2137 and 2142 make an energy conveying connection between cable connection terminals 2135 a and 2145 a, and the ports 2139 and 2144 make an energy conveying connection between cable connection terminals 2140 a and 2150 a. Further, the relative position of the front port 2137 to rear port 2142, and from front port 2139 to rear port 2144, defines a second direction. The angle between the first direction and the second direction may be between 30 degrees and 90 degrees, depending on how port assembly 2130 a is rotated. Moreover, the port assembly 2130 a may be translated at least along the first direction. Notably, the angle between the first direction and the second direction of between 30 degrees and 90 degrees is applicable to all the port assemblies in FIG. 21, as is the capability of being translated at least along the first direction.

In addition, it is noted that for any one of the patch panel subassemblies in FIG. 21, e.g., subassembly 2105 a, the port assemblies, e.g., port assemblies 2110 a to 2110 n, are individually translatable along a direction parallel to a surface of the mounting means, e.g., mounting plate 2115 a. Further, since the port assemblies are individually translatable, a distance between a port of one of the port assemblies and a port of another one of the port assemblies is changeable by moving one or both of the one of the port assemblies and the another one of the port assemblies. Still further, it is noted that the port assemblies in FIG. 21 are individually rotatable such that for any one of the port assemblies, e.g. port assembly 2152, an axis, e.g., axis 2154, passing through the center of a front port of the one of the port assemblies and through the center of a corresponding rear port of the one of the port assemblies is positionable to be non-parallel with an axis, e.g., axis 2158, passing through the center of a front port of another one of the port assemblies, e.g., port assembly 2156, and through the center of a corresponding rear port of the another one of the port assemblies.

Turning now to FIG. 22A, there is shown a perspective view of a portion of the rack mount patch panel unit 2100 of FIG. 21 with the depicted port assemblies in neutral positions. For example, ports 2160 a to 2160 l of subassembly 2105 b are evenly spaced along a mounting plate 2115 b with their longitudinal axes parallel to one another. FIG. 22B shows how selected ones of the port assemblies depicted in FIG. 22A may be moved from their neutral positions to allow easy access to port assembly 2160 f. As can be seen from FIG. 22B, port assembly 2160 e has been translated in the −X direction and rotated clockwise when viewed from the +Z direction, and port assembly 2160 g has been translated in the +X direction and rotated counterclockwise when viewed from the +Z direction.

FIG. 23B is a plan view of port assemblies 2160 e, 2160 f, and 2160 g of FIG. 23A. The figure shows a width dimension A of port assembly 2160 g, although each of port assemblies 2160 a to 2160 l has the same width, and thus the width dimension A is a common to the port assemblies 2160 a to 2160 l. Further, FIG. 2B shows a spacing distance B between port assemblies 2160 e and 23160 f, although the spacing distance between any two adjacent port assemblies of port assemblies 2160 a to 2160 l is B, when the port assemblies 2160 a to 2160 l are in their neutral positions. In some embodiments, the spacing distance B is in the range of approximately two percent of the width dimension A and approximately twenty percent of the width dimension A.

FIG. 23C is a plan view of the middle row of FIG. 22B. The figure shows how the port assemblies 2160 a to 2160 l may be arranged to allow easy access to port assembly 2160 f. As can be seen from the figure, port assemblies 2160 a to 2160 e and 2160 g to 2160 l have been moved from their neutral positions, and the port assemblies 2160 a to 2160 l are no longer spaced from each other by a spacing distance B.
